Actually, you bring up an interesting point - perhaps Apple already does wean off users from free options. Perhaps this is a move directed at consumers and not game producers.
Apple stands to gain nothing if users don't pay up - 30% of 0 is 0. Therefore they need to eliminate 0-dollar items from the market - but you can't go straight and do it because it would cause an uproar. So they make it infeasible for game developers to offer free games, and will extract the selling commission from the resulting non-zero priced games.
